Answer:
$3.5
Step-by-step explanation:
We have been given that Tyler baked 702 cookies. He sold them in boxes of 18.
First of all we will find the number of boxes of cookies by dividing 702 by 18.


We are told that after selling all the boxes of cookies for the same amount each he earned $136.50. To find the cost of each box we will divide 136.50 by 39.


Therefore, the cost of one box of cookies is $3.5.
Answer:
20 +/- $6.74
= ( $13.26, $26.74)
The 90% confidence interval for the difference in average amounts spent on textbooks (math majors - English majors) is ( $13.26, $26.74)
Step-by-step explanation:
Confidence interval can be defined as a range of values so defined that there is a specified probability that the value of a parameter lies within it.
The confidence interval of a statistical data can be written as.
x1-x2 +/- margin of error
x1-x2 +/- z(√(r1^2/n1 + r2^2/n2)
Given that;
Mean x1 = $200
x2 = $180
Standard deviation r1 = $22.50
r2 = $18.30
Number of samples n1 = 60
n2 = 40
Confidence interval = 90%
z(at 90% confidence) = 1.645
Substituting the values we have;
$200-$180 +/-1.645(√(22.5^2/60 +18.3^2/40)
$20 +/- 6.744449847374
$20 +/- $6.74
= ( $13.26, $26.74)
The 90% confidence interval for the difference in average amounts spent on textbooks (math majors - English majors) is ( $13.26, $26.74)

Step-by-step explanation:
If you have any questions about the way I solved it, don't hesitate to ask me in the comments below =)
<span>The y-intercept of a function is given by the initial value of a function. It is the value of the function when x = 0.
Given the functions
A. Blake is tracking his savings account with an interest rate of 5% and a original deposit of $6.
The y-intercept for this function is the initial deposit which is $6.
B.
x g(x)
0 6
1 2
2 10
The y-intersept for this function is 6 which isthe value of the function g(x) when x = 0.
C. The function h of x equals 4 to the x power, plus 3
When x = 0,

Thus the y-intecept is 4.
D. j(x) = 10(2)^x
when x = 0,

Thus, the y-intercept is 10.
Thereforen the function with the highest y-intercept is

which has a y-intercept of 10.
